Dataset creation tool based on CTC-Segmentation
|
|
-----------------------------------------------
|
|
|
|
This tool provides functionality to align long audio files and the corresponding transcripts into shorter fragments
|
|
that are suitable for an Automatic Speech Recognition (ASR) model training.
|
|
|
|
More details could be found in [this tutorial](https://github.com/NVIDIA/NeMo/blob/main/tutorials/tools/CTC_Segmentation_Tutorial.ipynb).
|
|
|
|
The tool is based on the [CTC Segmentation](https://github.com/lumaku/ctc-segmentation):

abstract="Recent end-to-end Automatic Speech Recognition (ASR) systems demonstrated the ability to outperform conventional hybrid DNN/HMM ASR. Aside from architectural improvements in those systems, those models grew in terms of depth, parameters and model capacity. However, these models also require more training data to achieve comparable performance.",
